Yes, I agree with Shirshendu Roy

I see your point. As specialization narrows, the number of experts in the field diminishes and so your "peer review" is likely to be performed by either a rival or a friend.

Unfortunately, working jointly with either your pals or your rivals (or both) would narrow the field even further!

Christopher C Rout yes, that is exactly what I mean.

So, how to get the whole picture (from several narrow fields), doing science the way it is currently done? I see only a deadlock.
